Compressive Properties of Rubberized Lightweight Aggregate Concrete
Rubberized lightweight aggregate concrete (RLC) is produced by partially replacing the fine aggregate of lightweight aggregate concrete (LC) with rubber particles. The compressive mechanical properties of RLC and its microstructure were investigated in this study. The results showed that the compressive strength and elastic modulus of RLC decrease gradually with the increment of rubber content, but the failure patterns exhibit obvious ductility. Moreover, it was found with polarizing microscope and micro-hardness testing machine that there are more pores in the interracial transition zone of lightweight aggregate concrete mixed with rubber particles. The bond between rubber particles and the cement paste was sastifactory due to the special structure of the rubber particle surface.
